Evaluation of Bridge Deck Wearing Surfaces and Protective Systems
The different wearing surface systems used by the Maine Department of Transportation (MDOT) were evaluated for their effectiveness in reducing penetration chlorides into the deck concrete and their durability in providing a smooth riding surface and the results are contained in the report. From a historical data base of the 1,822 concrete bridge decks currently maintained by MDOT, 119 bridges were selected for detailed field inspection. The field inspection consisted of measuring the following: chloride content of the deck concrete; areal extent of delamination, scaling, spalling and patching; and extent of cracking. The data showed that for as-built wearing surfaces, bituminous concrete overlays with a membrane were more durable and effective in preventing chloride content increases in the deck concrete than reinforced concrete overlays or integral concrete. Similarly for replacement wearing surfaces, bituminous concrete overlays with membrane waterproofing were more durable and effective than unreinforced conventional concrete overlays. The data suggested that latex modified concrete overlays were more durable and effective than reinforced or unreinforced conventional concrete overlays.
